SPECIFICATION forming part of LettersPatent No. 462,502, dated November8, 1891.

v Application filed May 29.1890. Serial No. 353.657. (No model.)

T0 all whom t may concern.-

Ie it known that I, JAMES F. MCELROY, a citizen of the United States,residing' at Al bany, in the county ef'Albany and State of New York,have invented certain new and useful Improvements in Car-Heaters, ofwhich the following is a specification, reference bein had therein tothe accompanying d rawings.

This invention relates to new and useful improvements in car-heaters5and it consists in the peculiar construction of a magazinestove designedto give the best results in econo my of fuel, together with safety incase of accident, and, further, in the peculiar construe tion,arrangement, and combination of the varions parts, all as more fullyhereinafter described, and shown in the accompanying drawings.

In the said drawings, Figure l is a front elevation. Fig. 2 is avertical central section on line x x. Fig. 3 is a plan, and Fig. #l is ahorizontal section on line y y.

A is the base, preferably cast, and having cast integral therewith theash-pan B. This base has an annular shoulder C, which supports the outershell D. This shell I preferably make by taking wrougl'lt-iron pipe ofsuitable diameter and cutting off a section of Y suitable length, thusforming a seamless casA ing.

E is the cap, having the annular shoulder F and iiange G, the shoulder Fresting upon the top ofthe casing D. The cap is provided with anupwardly-extending collar Il, forming within the smoke-exit. The cap iscentrally apertured to form a feed-opening, and around this aperture isformed the guide-flange I, the aperture being covered by a suitablecover J, pivoted upon the pin J, and held together in position by meansof the spring J2 between the head of the pin and the top of the cover.The cover 'is provided with a locking-recess, which engages with thestud J 3 upon the top casting, being held in its locked .position by thespring J2.

lVithin the easing and across the upper end thereof is secured theperforated plate K, which has upwardly-extending flange L, by means ofwhich this plate is bolted to the outer casin The plate K is centrallyapertured, and around this aperture is secured the depending guide-plateM, which has the extension N at one side, having guides N formedthereon, into which the sliding cover O engages. This cover has asuitable handle I) extending through the top, whereby the aperture maybe opened and closed by sliding` the cover forward or back.

Q is the smoke-chamber formed between the top plate E and the perforatedplate K.

Ris the grate supported on the standards S, which likewise support the`lire-pot S. This fire-pot is provided with the annular iiange d, whichsupports the inner casing h, which is provided with aninwardly-extending flange c, within which is secured the upper sectionsdof theinner casing. An air-space@ is formed between the two casings.Tithin the inner casing I form a magazine by means of the coil T, whichenters through the casings at f and is coiled within the inner casing,the lowermost helix of the coil g being au open or separated coil andthe upper coils being closedthat is, wound so closely together as toform within the magazine-chamber, the coil finding exit at the upper endat 7L.

Between the coil and the inner casing is formed the coinbuStien-chamber`1I.

The parts being thus constructed, their operation is as follows: Theoperator to till the stove opens the door J and the sliding cover O. Thecoal is then poured in through the feed-opening, filling the magazinewithin the coil. A tire being started in the grate, the products ofcombustion will tind exit through the colnbustionchamber t', thencethrough the perforations in the plate K into the smokechamber, andthence through the smoke-exit in the stove-pipe. The lower open coilswill be heated by the body of the coal resting within and by the heatfrom the products of combustion passing without.

j is the aslrdoor, which I make of suitable size, so that any part ofthe grate may be removed therefrom.

In case ot accident the perforated plate K and top plate E will preventany coal from getting out in case the stove is upset, and if the stoveis not upturned the door J will remain closed by gravity. The air-spacec be- IOO tween the two casin gs will prevent the outer case frombecoming excessively hot, as said air-space connects into the ash-pitbeneath, so that a draft ot' air can pass therethrough at all times,suitable dampers 7c being provided in the ash-door for the draft. i' ByInakiug the magazine Within the coil I am enabled to get the bestresults in heating the Water which passes through the coil and ineconomy in the manufacture of the stove. of coal Within the coilpreventsdamage to the coil in ease of collision. The heat of the coal inthe magazine is imparted to the coil and is suflicient to keep the watercirculating long after the ireY is out. I am also enabled Wto make amagazinestove which in ordinary railroad use will last for twenty-fourto fortyeight hours Without replenishing.

What I claim as my invention is- 1. In a car-heater, the combination ofa casing, a Water-circulating coil coneentrically arranged with thecasing, arranged to form a fuel-magazine Within the coil, and a combus-The body tion-chamber within the easing outside the coil, a fire-pot,and a top having a feed-opening connecting into the fuel-magazine,substantially las described.

2. In a car-heater, the combination, with the casing and cover havingafeedaperture therein, of a pivoted door having a locking-recess, alocking-lug on the casing, and a spring, such as J2, upon the pinholding the door upon the lug, substantially as described.

3. In a car-heater, the combination, with the casing, of the top E,having a feed-opening therei n', perforated plate K,formin g thesmokechamber Q, a cover O, sliding in guides N', the handle P, and coverJ, substantially as described.
